INSTRUMENT HOLDER OR CLAMP;

Application filed March 19, 1917.

To all whom t may concern:

Be it known that I, CONSTANT S. RoUNDs, a citizen of the United States of America, and resident of Flint, in the county of Genesee and State of Michigan, have invented certain new and useful Improvements in Instrument Holders or Clamps, of which the following is a specification.

This invention relates to instrument holders or clamps and particularly to a device for holding scales or measuring devices and other tools used by Workmen.

An object of this invention is to provide a novel clamping device for holding scales, rules, and also for holding a pencil, the said device being applicable to abelt, apron, or coat worn by the workman so that the holder may be within convenient reach and the implements accessible. It clamps on the outside or inside of pocket so that the pocket proper may be still used. v

lVith the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this speciication, wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a view in perspective showing the holder with the support therefor illustrated in dotted lines;

Fig. 2 illustrates a side elevation thereof; and

Fig. 3 illustrates a sectional view on the line 3-3 of Fig. 2.

rfhe clamping member is preferably constructed of a plate or strip of material bent on itself to form a loop 4c, a back 5 and a front 6, the said loop being rounded to form a socket or holder for a pencil 7. rEhe edges of the overlying portions opposite the loop 4 are secured by a binding strip 8 which embraces the said edges, and said binding strip is secured to the back and front by means of fastenings such as screws 9. In order to hold the back and front in spaced Specification of Letters Patent.

relation to each other and to create a clearance for the reception of scales or rules such as 10, spacing strips 11, 12 and 13 are interposed between the said back and front and are held in place by fastenings such as the screws lt, although the spacing strip 13 is held in place by the screws 9.

The lower ends or edges of the front and back are free and form jaws 15 and 16 which bear against and retain the devices in the clamp against accidental displacement and in order to insure proper frictional engagement of the jaws with the instruments they are to hold, the jaws are reinforced by a spring 17 consisting of spring metal which'is bent to lie approximately parallel with the edges of the said jaws and the said spring metal is secured to the jaws by curling the edges 18 and 19 so that they form seats to hold the said spring material. By reason of the construction just indicated, instruments such as rules or gages applied to the holder cause the jaws to separate to a suiiicient degree to permit the introduction of the implement and there is suflicient rigidity of the spring metal to retain the implements therein.

In order to aiord a means for securing the clamping member to a belt or garment, the back 5 is supplied with clips 20 and 21 which are anchored in place by the screws 9 and 14. The construction of the clips is well shown in Fig. 3 of the drawing and the manner of securing them to the back is also fully illustrated, so that a workman may readily apply the clips to a belt or to a waist band of a garment or pocket of any garment and he can with ease remove them.

I claim- 1. In a clamp for scales, a clamping member comprising a strip of material bent on itself to form a socket, means for binding the edges of the strip together, jaws formed as parts of said strip, means for yieldingly holding the jaws in engagement, and means for supporting the said holder.

2. In a clamp for scales, a clamping member comprising a strip of material bent on itself to form a socket, means for binding the edges of the strip together, jaws formed as parts of said strip, means for holding the jaws in operative relation comprising a spring connecting the said jaws7 and nie'ans for anohoringthe spring to the 5 jaws. Y

3. In a clamp for scales, a clamping member comprising a strip of material loeniI on itself to form a socket, means for binding the edges of the strip together, jaws formed as parts of said strip, means for holding the jaws in operative/fl relation comprising a Spring connecting the said j aws, and seats formed on the jaws for holding said spring.
